To all whom, it may concern.-

Be it known that I, LUOIUS E, COLEMAN, a citizen of the United States, residing at Santa Ana, county of Orange, State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

My invention relates to a burner designed to burn the light grades of crude petroleum, kerosene, and distillate from crude petroleum; and the objects thereof are to producea burner which will burn such fuel with a minimum amount of smoke and which is of simple construction and is easily operated and cleaned. I accomplish these objects by the burner described herein and illustrated in the accompanying drawings, in which- Figure 1 is a Vertical section on the line 1 l of Fig. 2. Fig. 2 is a plan of the top of the burner.

In the drawings, A is the casing of the removable vertical retort-chamber B, which is preferably made of cast-iron. Cast integral with the top of the retort-chamber are the spreader-plates 0, having cup-shaped depressions D in the top. The bottom of the retort-chamber is preferably cone-shaped for convenience in cleaning it. In the bottom of the casing of the retort-chamber is screwed a bushing E, through which passes in threaded contact the vapor-pipe F, which extends from near the top of the retort through the bottom thereof, where it branches into two or more branches, each of which terminates.

in an upturned end or burner-tip H below the center of the spreader-plates, which is provided with a vapor-port I, through which the vapor is discharged upward against the center of the spreader-plate. The object in using a bushing in the bottom of the retortchamber is to facilitate cleaning the chamber, and, if desired, it may be omitted and the vapor-pipe be screwed directly into .the bottom of the casing of the retort-chamber. Liquid fuel is supplied into the retort chamher through supply-pipe J, which supports and holds the retort-chamber in placein the combustion-chamber. (Not shown.)

Extending from end to end and from side tosideofthecombustiou-chamber (not shown) is bed-plate K, which is provided below the burner-tipswith starting-cups L, which will holdasufficient quantity of liquid fuel, which when burned will heat the retort hot enough to generate the liquid fuel into vapor. The

bed-plate is provided with draft-opening M,

cieutlyheated the supply of liquid fuel is againturned on, which is vaporized in the retort, and the vapor passes out through the burnertips and is projected against the spreaderplates, where it mixes with the air and burns in a clear white flame with but little, if any, smoke. It will be observed that the vapor is taken from the retort near the top and is led centrally therethrough and out at the bottom and that the pipes which carry the vapor are not subjected to the direct action of the flame, thereby greatly prolongingthe life of the pipe. Anotheradvantage in this construction is that any residuum which may be deposited in the retort-chamber is deposited therein below the mouth of the vapor-pipe, and therefore will not clog it. There is a small amount of residuum deposited in the retort chamber, which can easily be cleaned out byunscrewing the chamber from the bushing without disturbing any of the other parts,which leaves a good-sized opening, through which such deposit may be removed, the conical shape of which may be deposited in the stove or pipe in starting the fires.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A hydrocarbon-burner comprising a removable vertical retort-chamber; a spreaderplate affixed to the casing of said retort-chamber at the top thereof; a vapor-pipe commencing within said chamber extending from near the top of said retort-chamber out through the bottom thereof and extending thence and terminating centrally below the spreaderplate; a burner-tip on the end of said vaporpipe below the spreader-plate; a fuel-supply pipe opening into said retort-chamber; a-bedplate below the vapor-pipe having a draftopening therethrough disposed to one side of the burner-tip.

2. A hydrocarbon-burner comprising a removable vertical retort-chamber; spreaderplates alfixed to the casing of said chamber at the top thereof, one on each side thereof; a vapor-pipe commencing within said chamber near the top thereof and extending out through the bottom thereof and branching into branches, each one of which branches terminates below a spreader-plate; a burnertip on the end of each branch; a fuel-supply pipe opening into said retort-chamber; a bedplate below the vapor-pipe having a draftopening extending therethrongh between the said burner-tips, and having starting-cups therein disposed below said burner-tips.

In witness that I claim the foregoing I have hereunto subscribed my name this 30th day of June, 1902.
